The updated military specifications for firefighting foams marked a significant shift for U.S. Department of War (WoW) installations globally and commercial airports in the US. It also set a trend for other industries which use fluorinated firefighting foams, like aqueous film-forming foams (AFFFs).
AFFFs have been identified as a major cause of PFAS contamination. Under the new specifications, operators at U.S. military sites, U.S. commercial airports and other businesses now have access to fluorine-free firefighting (F3) foams, which can effectively extinguish fires without the use of PFAS.
“The majority of airports outside of the US have been using F3 foams for over a decade, after the first modern synthetic F3 foams were first launched as products in 2003,” said CDM Smith's Ian Ross. “While this specification applies to U.S. military fire scenarios, it sets a new trend in the U.S. that may help with the transition away from AFFF use.”

The new specifications introduce an option to migrate away from PFAS-laden foams, but one significant challenge will be the effective decontamination of existing fire suppression systems. According to Greene, there are several important steps to consider:
- Drainage and disposal of existing AFFF
- Multi-rinse cleanout
- Cost-benefit analysis of cleaning approach and agents used
- Pre- and post-sampling to determine effectiveness of cleanout
